Lesser Star Coral

About

Lesser Star Coral (Paragoniastrea australensis) is a large-polyp stony coral with the characteristic geometric, star-like corallite patterns typical of the family Merulinidae. Found across an impressive natural range spanning the Indo-Pacific and into the Southwest Atlantic, it grows from shallow nearshore reefs down to around 40 meters depth, which tells you something about its adaptability to varying light and water conditions. In the wild it tends to form solid, domed or encrusting colonies that become substantial over time, contributing to reef framework structure much as you would expect from a hardy faviid-type coral. In the aquarium it is generally considered an intermediate-level coral rather than a beginner's choice, not because it is especially fragile, but because it rewards consistent, stable husbandry more than it tolerates neglect or swinging parameters. Moderate lighting and moderate flow suit it well, and it appreciates regular feeding to supplement what its zooxanthellae provide. Aggression is worth keeping in mind. Like most large-polyp stony corals, it can extend sweeper tentacles at night, so give neighboring colonies a reasonable buffer. Overall it is a solid, dependable reef coral that earns its place through longevity and a satisfying, architectural growth form rather than flashy coloration.
